Google's first smartphone, the T-Mobile G1, made its official debut Tuesday morning in New York. The $179 device, which is manufactured by HTC, is the first phone to use Google's open source Android operating system. Like Apple's iPhone 3G, the G1 has full touch-screen functionality and works on both Wi-Fi and 3G networks. But does this new smartphone pack enough muscle to topple Apple's iPhone? Below is a rundown of the G1's specs and how they compare to the iPhone 3G.

It has a bulkier footprint, weighs more, and packs a smaller screen than its competition. In addition, the G1 only comes with a paltry 1GB of memory (although you can expand it). Fortunately, the phone makes up for those shortcomings with a built-in five-row QWERTY keyboard that slides out from underneath the device's touch screen.
